Subject: Abort on "impossible" condition.
X-Git-Tag: v1~124
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/9c74709264a831cc13e8295579f4188b3c62b3e5

Abort on "impossible" condition.

A corrupt or otherwise invalid cdecl structure could make the
explain_prologue function fail to return a value.  Add an assertion to
catch that.
